It'll be a girl, or "guidette," for "Jersey Shore" alum Jenni "JWoww" Farley.

The pregnant 27-year-old reality-TV star shared the news with Us magazine, adding that she and fiance Roger Mathews were "super excited and super emotional" to find out their baby's gender.

"I pictured a boy this whole time, so when I saw 'girl' on the paperwork, I was like, 'No way!' But deep down I think I knew," she said. "[Snooki's son] Lorenzo is gonna have a BFF, and I couldn't be happier!"

Snooki, of course, is Farley's BFF and "Snooki & ww" costar Nicole Polizzi, who welcomed her son with fiance Jonny LaValle in August 2012. Farley told People magazine that they couldn't wait for the arrival of their "little princess and Lorenzo's future girlfriend."

As for Mathews, the proud papa-to-be was a little preoccupied with demystifying the female psyche all over again.

"Been 4 years trying to figure out one girls brain. Now I get to try and figure out another one. Grey hair is in my immediate future," he tweeted, telling a follower he had his work cut out for him because "Mom is half crazy and that's a strong gene."
